In the initial âexpandingâ phase, lymphatic fluid flows at an increased rate and volume from an affected joint to the draining LN via afferent lymphatic vessels. The LN volume expands, presumably to accommodate the influx of cells and lymph exiting the inflamed synovium.
COPD exacerbation. Many people with COPD have attacks called flare-ups or exacerbations (say egg-ZASS-er-BAY-shuns). This is when your usual symptoms quickly get worse and stay worse.

More shortness of breath than usual. Greater tightness in your chest.
